I thoughts about it in this way:
Everything has pros and cons ... As - like me - beginner here, trying to get attention is most important.
Yesterday I wrote article, and after 7 hours only one person saw it. I don't have cash right now to promote it so my article was nearly dead at the beginning, so the time I had to spend for it was wasted beaucse this article have potential - for me - I just choose to "delete it" and bring it back when I will be minnow or something.

That's shows me more regulus of being part of Steemit. Everybody wants coin and few people have this coins so they use it promote article because promotion gives coin(s) to everybody.

I realized that right now at Steemit without many followers or cash to promote your article is dead even before you start to create it because only 1 or 2 people read him. So pros are simple, if you already have some attention you are good, but right now without $$$ it's hard to get attention.
You invest your time here in exchange for some profits, if I can get 0.5$ just for creating good commentary and I will for it spend 5-15 minutes it's more interesting for me to gain cash in that way than spending 2 hours to create something and achieve nothing. Witchout $$$ I cant promote my stuff, so nobody will see it. That's how this coin is so powerful here.

Second side of it is that your post is dead without promote because SO MENY people do many stuff connected to Steemit that you upload your work and refresh the site and POOF its gone in space and time of memes, films, pictures and many more :D

So people here wants to be fallowers to Whales not minnows. People want's cash and attention that's why they create good posts, good comentary and also trash like "Good post! I Like... Check my blog too!" and few more things just for gathering cash to gain more attraction.

And attraction will gain more cash :D

I hope that my comment wasn't too confusing
